Fintan's method of painting is characterised by an exploration of pigments and their configurations. He works with a combination of varnishes and oils, using techniques that have been perfected over many years, despite the art’s serendipitous appearance. His abstracts are worlds eliciting a multitude of emotional and intellectual responses that we, as viewers, must resolve.

Fintan’s work has been exhibited and acquired by numerous collectors across North America, Europe and Australia, and featured in prominent residential projects in the UK and USA. He is an Artist in Residence at Chelsea Harbour Design Centre (London) and member of BBK (Federal Association of German Fine Artists).
